Improper Input Validation in Jetty

  • Disclosed: 14.05.2022
  • Updated: 11.10.2026 12:21

Jetty 8.1.0.RC2 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
